## Abstract The effect of salts on the coil‐to‐helix transition of poly‐α‐amino acids was investigated by optical rotatory dispersion and potentiometric titration techniques. Both charge‐dependent and charge‐independent contributions to the free energy were considered. The free energy of formation
## Abstract α,β‐Unsaturated lactones or lactams 1 react with hydrazines 2 via Michael‐like addition and subsequent ring transformation by nucleophilic attack of the hitherto unchanged hydrazine nitrogen atom at the carbonyl carbon atom. The addition is highly trans‐stereoselective, thus affording o
